Question

Tangent drawn to parabola y²=8x at points p(t1) and q(t2) intersect at a point t and normal at p and q intersect at r such that t1 and t2 are root of equation t² +at + 2=0

Answer 1

Answer:

prove that the point of intersection of the tangents at't1' and 't2' on the parabola y²=4ax is [at1t2 , a(t1+t2)]
